BOTTLE covnn, ESPECIALLY ADAPTED FOR THE usn WITH MILK BOTTLES.

Application filed September down the side of the bottle, entailing a waste of milk and soiling the table-covering; again since the paper cover is removed and replaced by hand every time the. bottle-1s used, the paper stopper may become a source of contamination. In addition, since the top every time milk is poured out, the risk 1s run that it may become contaminated as it pours Over the edge. The device shown in the accompanying sketch serves to eliminate j all these disadvantages in a simple and effective manner." Fig. 1 represents a plan view of the device; Fig. 2, a cross sectlon along line 2-2 of Fig. 1. v

The device consists of a cap 11 which may be of metal, rubber or any other suitable material integral with which are three symmetrically placed spring clips 12 and spout 13. The spout is covered with a flap 4 hinged at 5. At 6 is provided a rubber gasket. The device is used as follows. The ordinary paper cover is removed in any desired maner. I For convenience two prongs 7 are provided which may be used to advantage to remove the cover; although these prongs are shown as continuations ofv the shoulders which support the pivots of the flap 4, they ma be located at any other convenient part 0 the cover. 7

After the paper cover has been removed the cap 11 is snapped into place. The spring clips 12 are so designed that as they press against the torus shaped top 9 of the bottle they pull the cap .11 downward, the

rubber gasket 6 making a fluid tight joint between the cap and the bottle.

WVhen the contents ofhe bottle is poured out through the spout 13 the. flap 4 is raised by the pressure of the liquid. At 10 the edge of the bottle is always exposed,

flap is slightly bent and turned in under the cap, allowing air to enter the bottle to displace the fiuid being poured. out through the spout. WVhen the bottle is set in a vertical position, the weight of the flap 4 brings it into position to cover the spout and to close the opening at 10 thereby protecting the contents of the bottle from contamination.

It is evident to anyone skilled in the art that departures from the particular design shown may be made without deviating from the spirit of the invention disclosed in the foregoing description and as claimed below. Thus, for example, the spring clips 12 might be replaced by a rubber adapter or may be made separate from the cap 11, etc.

What I claim is:

A cover for an open-topped receptacle comprising a cap adapted to seat on the open top of the receptacle and having means for securing the cap to the receptacle when seated on the said open top, the cap having an opening and an open spout extending from the opening, a flap intermediately hinged to opposite sides of the opening, the flap having a body portion for covering the opening, a lid on one side of the hinge for resting against the open spout to close the spout when the flap occupies its normal position, and an extension at the other side of the hinge that extends into the opening and under the cap to engage the underside of the cap when the flap occupies its normal position, the portion of the flap on the spout side of the hinge being heavier than the portion of the flap on the extension side of the hinge, whereby the flap is adapted to occupy its normal position by gravity when the receptacle occupies its normal position with its open top uppermost, and whereby, when the receptacle is tilted from its normal position, the flap will pivot from its normal position about the hinge in response to the pressure exerted upon the lid by the contents of the receptacle.
